This invention relates to that type of metal window glass channels which are primarily designed for use in closed automobile bodies to receive the edges of the window glass employed therein, and more particularly to means for installing the same.

it is usually desirable toinstall these channels after the construction of the body has been practically finished and while the installation in casing grooves thereof about the window-openings has not involved serious difficulty, such installation in the enclosed space into which the window is lowered has been found to be particularly difiicult, as means for securing the channel in position like that used about the opening cannot be employed. The object of my invention is toprovide a form of metal channel or guide. for the edge of the window glass, which may be readily inserted in the position in which it is to-be held from the top of the enclosed space below the window opening, and which will be se curely held in the position in which it is inserted. v

I accomplish this object by means of the construction hereinafter described, and .as illlllistrated in the accompanying drawing in W ich: a

Fig. 1 is afrontelevation of a window glass channel embodyingmy invention and shown in position in a casing.

Fig. 2 is a sectional. view at line 22 of' Fig. 1.

Fig 3, is a sectionalvview at line 3-1-3 of Fig. 1-.

Fig. 4 is a side elevation of the lower end. portion of a window glass channel embodying my invention.

In the. drawing, a, indicates a casing located directly beneath a window opening and adapted to receive the window glass when lowered therein, and 6 indicates the top rails between which the'glass slides. A sheetmetal window glass channel 0 of the type shown in my prior Patent No. 1,571,831 is provided, said channel having a bottom, or base and two sides and being preferably felt lined and ada ted for use in connection with a similar gui e in the casing of the window opening in the manner indicated in my Patent No.- 1,635 570.

According to my invention a series of s nel at suitable intervals, each tongue being grooves, as shown in Fig. 2.

es (1 are cut from each side of the chan-= formed by a longitudinal slit intermediate the side and two transverse slits extending from the ends of the longitudinalslit to the base, and being bent outward from the side into approximately the plane of the base. Whether the tongues are opposite each other; or alternately placed is notimportant, 'sof ar as their functions are concerned, and the number employed may be varied according to conditions.

In the construction of the body a guideway 6, which merely consists of a fiat strip of metal,having its edge portions bent inward to form oppositely disposed grooves f, is socured to the inner side of the casing on which the channel is to be located, and extends from top to bottomthereof, said groove being adapted and arranged to receive the end por-v tions of the tongue (1, when inserted therein,

so that, to install the channel, it is merely necessary to slide the same downward in the guideway, the tonguesd extending into said .As the metal from yvh'ch the tongues are formed is thin, it is difficult to form the grooves in the guideway so that the tongues will fit closelytherein. To obviate this difliculty the tonguesare'bent obliquely at one end portion thereof, so that the eifective thickness thereof is increased to correspond to the width of th'egrooves and a portion of each tongue will bear on each side of the groove in which it is located.

As the mater'i l of hich the channel is formed is somewhat resilient, a. firm engagement of the tongues with the guides will be secured at all times and the danger of rattling in the future will be avoided.

To provide a stop for supporting the channel in position, one or more prongs 9 may be struck out from the metal of'the guide 0,

which will.,engage the base portion of the channel, as'shown in Figs. 1 and 3, and,'for the purpose increasing the rigidity with which the channel is held, the sides of the channel are preferably cut from their'edges to the base and laid flat with the base and then bent double to form a reenforced endportion it having projecting tongues d.

With the above described construction, the channel may be readil inserted after the door, or other construction has been finished,

and, when in position will berigidl held so that all possibility of rattling will avoided. The form of guide shown is not expensive and less expensive forms may be employed.

The tongues may be formed from the channel by a simple mechanical operation.

. having oppositely .dis'poscd I claim:

1. In combination with a casing, a sheet metal window glass channel composed of a base and two sides and having one or more tongues cut from each side and bent outward in position to project laterally there-from adjacent the base and a vuideway secured to the casing having oppositely disposed grooves arranged to receive said tongues.

2. In combination with a casing, a sheet metal window glass channel composed of a base and two sides and having one or more tongues cut from each side and bent outward at the base to project oppositely approximately in the planethereof and a guideway secured to the casing and having oppositely disposed grooves arranged to receive said tongues.

3. In combination with a. window casing,

grooves, a window glass channel of somewhat resilient sheet metal and composed of a base and two'sides, said channel having one or more tongues cut from each side and bent outward therefrom to project into said grooves from adjacent the base, said tongues having their end portions bent obliquely with relation to the sides of the grooves for resilient engagement.

4. In combination with a window casing, having oppositely disposed parallel grooves, a resilient metal window glass channel having tongues formed therewith and projecting beyond its sides adjacent its base and slidably engaged in said grooves, the distance between the .adjacent sides of the grooves being substantially greater than the thickness of the metal from which the tongues are formed and said tongues each having a portion bent obliquely to another portion thereof thereby to provide opposite faces for resilient engagement with the sides of the groove. I

5. In combination with a window casing having a pair of gui'deways disposed in parallelism and opening towards each other at opposite sides of the plane in which the window glass is to be held and a sheet metal channel for receiving the edge portion of the window glass arranged with its base portion between said guideways and having one or more tongues cut therefrom and bent outward at each side adjacent the base in position to en gage the sides of the uideways which 'face towards the casing am? hold the channel in position thereon. i

6. In combination with a window casing having a pair of guideways disposed in parallelism and opening towards each other at opposite sides of the plane in which the window glass is to be held and a sheet metal channel for receiving the edge portion of the window glass arranged with its base portion between said guideways and having one or more tongues cut'frorn each side thereof and bent outward adjacent the base in position to engage the sides of the guideways which face towards the casing and hold the channel in position thereon.

In testimony whereof, I have signed my name to this specification.
